Monolithically constituted gasket assembly with cover and hard disk drive unit

Abstract

A hard disk drive unit constituted in the following manner can prevent leaks of gas caused by a deformed gasket assembly, can enhance operational performances of the hard disk drive unit in accordance with using purposes and can be assembled more easily. A monolithically constituted gasket assembly with a cover for fitting to a case of the hard disk drive unit comprises: a cover plate constituting the cover made of aluminum, plastics and the like having piercing holes at predetermined positions; a gasket fitted to the cover plate via the piercing holes; and a ring constituting the cover arranged around an outer periphery of the gasket. A gap formed between the cover plate and the ring, and a gap formed between the cover plate and the case for the hard disk drive unit are sealed by the gasket.

1. A monolithically constituted gasket assembly with a cover for fitting to a case of a hard disk drive unit comprising:
 a cover plate constituting said cover having piercing holes at predetermined positions;  
 a gasket fitted to said cover plate via said piercing holes; and  
 a ring constituting said cover arranged around an outer periphery of said gasket, wherein:  
 a gap formed between said cover plate and said ring, and a gap formed between said cover plate and said case for the hard disk drive unit are sealed by said gasket.  
 
     
     
       2. A hard disk drive unit of which active components are accommodated in a case, wherein:
 a monolithically constituted gasket assembly with a cover for fitting to the case comprises a cover plate constituting said cover having piercing holes at predetermined positions, a gasket fitted to said cover plate via said piercing holes and a ring constituting said cover arranged around an outer periphery of said gasket, wherein:  
 a gap formed between said cover plate and said ring, and a gap formed between said cover plate and said case for the hard disk drive unit are sealed by said gasket.
